To all 'whom it may concern:

a part of this specitication, in which- Figure l is a side view of myimproved saw-set, partly in section, .to show the construction.

Figure 2 is a t'op view of the same. Similar letters of referenceindicate corresponding arts. p My invention has for its object tofurnishan improvedsaw-set for setting the teeth of circular and othersaws, which shall be simple in construction, convenient in use, andel'ective in operation, enabling the teeth to be all'set at the samepitch and at. any desired pitch; and

It consists in the construction and combination of the various parts, ashereinafter more fully described.

A is the handle of the instrument, upon th'e. forward part of which isformed, or to it is securely attached, theA stationary jaw B, the faceof which may From the face of the jaw B, at'or near one side,- projectsa square tenon, O, which maybe formed solid with the parts AB, and whichpasses through a square hole in the movable jaw D, which is held inplace upon the said tenon by a thumb-uut, E, screwed upon vascrew-thread cut upon the projecting' end of the said tenou C, as shownin iigs. 1 and 2. rlhis construction enables the jaws to be easily andconveniently adjusted at a distance apart corresponding'with thethickness of the plate of the saw to be operated upon.

Upon the lower side of the forward part of the.

shank of the handle 4A is formed an arm, F, through the lower vpart ofwhich is formed a mortise vto receive the gauge G, which has a scale ofdivision-marks formed upon its side, and-which is adjustably secured in'place by a set-screw, H, as shown in the drawing, so that the instrumentmay be yconveniently adjusted to give v'a greater or lesser set to theteeth, as may be desired, and when adjusted will give exactly the sameset toall the teeth.

Having thus described my invention, Y iVhat I claim as new, and desireto secure by Letters Patent, is- An improved saw-set, formed by thecombination of the handle A, stationary jaw B, having a scale ofdivision-marks formed upon its face, tenon O, adj ust# able jaw D,thumb-nut E, arm F, gauge G havingaI scale lof division-marks .formedupon it, and set-screw H, with each other, substantially as herein shownand described, and for the purposes set forth.
